Application |
|
Model
DEM331BL single phase electronic multi-rate front board installed
active energy meter is a kind of single phase
two wire three
tariffs (tariff conversion is controlled by timer outside or similar
equipment)active energy meter, the meter
completely accord
with relevant technical requirement of class 1 single phase active
energy meter stipulated in
international
standard IEC 62053-21. It can accurately and directly measure 50Hz or
60Hz active energy consumption
from single phase
AC electricity net. This meter has seven digits LCD monitors showing
various consumption data and
information. And
there are far infrared and RS485 communication module in it. It is use
for setting and reading the meter.
Contact with all
kind of AMR system conveniently. It has following features: good
reliability, light weight, specious nice
appearance,
convenient installation, etc.

Function and features: |
|
-- Front
board three fixed holes installation, the cover is made of PC
material which is
transparent and anti-UV molded overall,
the base of the meter and the terminal block are
made of quality bakelite material which is
moisture-resistant, fire-retardant,
high
temperature molded overall. It has following features:
good weatherability, high rigid, good
insulation
performance, etc.
--Have
two tariffs, and port of set the tariff, input control voltage 0-90
Vac, set up tariff F1,
input control voltage 150-400 Vac, set up tariff F2,
the tariff conversion is controlled by timer
outside or similar equipment.
--May
select cycle display (default) or push the button itemized display,
it can display 6 data
at most. Can select the data
which displayed. The decimal median which displayed can
choose set one or two.
--Use
memory that is not loss easy, the data can be kept forever after
power cut off.
--A
port of pulse output passive (polarity), complying with standard IEC
62053-31.
--There
are far infrared and a port of RS485 communication data. It is use
for setting and
reading the meter,communication protelot complying with
standard DL/T645-1997.
--Six
LCD instructions respectively power state, signal of power impulse,
the direction of the
trend of load current, the state
rates just now and the data communications state.
--Single
direction measure single phase two wire active power consumption. It
is nothing
with direction of the trend of load
current. Complying with standard IEC 62053-21.
--Direct
connect and use, there are two types you may select. Standard
configuration type 1B
connection, may select type
1A connection (Product Configuration code is AM).
--Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is AN). |
